Abstract
A multiband phased array antenna includes a substrate, and dipole element arrays extending outwardly from an imaginary center point on the substrate. Each dipole element array includes dipole antenna elements arranged in an end-to-end relation and having a dipole size different than a dipole size of dipole antenna elements of at least one other dipole element array. A ground plane is adjacent the dipole element arrays and has a different spacing therefrom in an outward direction from the imaginary center point. The different spacing between the ground plane and the dipole element arrays increases from the imaginary center point towards an edge of the substrate.
